Speed dome camera

Abstract

A camera includes a front portion, a rear portion and a electric brush connecting the front portion and the rear portion. The front portion includes a camera module for capturing image. The front portion further includes a wireless transmission module. The rear portion further includes a wireless receiving module. The front potion sends the image to the wireless receiving module by the wireless transmission module.

1 . A speed dome camera, comprising:
 a front portion including a camera module for capturing an image, the front portion further includes a wireless transmitting module;   a rear portion including a wireless receiving module; and   a electric brush connecting the front portion and the rear portion; wherein, the front potion sends the image to the wireless receiving module by the wireless transmitting module.   
     
     
         2 . The speed dome camera as claimed in  claim 1 , wherein the front portion further includes a front control module set between the camera module and the wireless transmitting module, the front control module sends the image from the camera module to the wireless transmitting module. 
     
     
         3 . The speed dome camera as claimed in  claim 1 , wherein the front portion further includes a PTZ control module connected to the camera module to control direction, angle of view, and zoom of the camera module. 
     
     
         4 . The speed dome camera as claimed in  claim 3 , wherein the rear portion further includes a rear control module connected to the wireless receiving module and the electric brush, the rear control module receives the image from the wireless receiving module, and drives the PTZ control module to control the camera module by the electric brush. 
     
     
         5 . The speed dome camera as claimed in  claim 4 , wherein the rear portion further includes a encoding module and a network connecting module, the encoding module encodes the image and sends the encoded image to the network connecting module. 
     
     
         6 . The speed dome camera as claimed in  claim 4 , wherein the rear portion further includes a power supply connected to the electric brush and the rear control module, the power supply provides electrical power to the rear control portion and also provides to the front portion by the electric brush. 
     
     
         7 . The speed dome camera as claimed in  claim 4 , wherein the rear portion further includes a communication interface connected to the rear control module for connecting a display. 
     
     
         8 . The speed dome camera as claimed in  claim 7 , wherein the communication interface is a RS-485 interface. 
     
     
         9 . The speed dome camera as claimed in  claim 1 , wherein the wireless transmission module and the wireless receiving module are a radio frequency device, a BLUETOOTH device, or a communication device.
